In a simple pendulum of length

10 \mathrm{~m}

, string is initially kept horizontal and the bob is released.

10 \%

of energy is lost till the bob reaches lowermost position. Then find speed of bob at lowermost position.

View answer and explanation

Correct option: B

6 \sqrt{5} \mathrm{~m} / \mathrm{s}

Option B (

6 \sqrt{5} \mathrm{~m} / \mathrm{s}

) is correct because it is calculated using the conservation of energy principle, accounting for the 10% energy loss.

. If the coefficient of restitution is 0.6 , the height to which the ball will rebound is A running man has the same kinetic energy as that of a boy of half his mass. The man speed up by

2\mathrm{\;m}{\mathrm{s}^{ - 1}}

and the boy changes his speed by

x = \mathrm{m}{\mathrm{s}^{ - 1}}

, so that the kinetic energies of the boy and the man are again equal. Then x in
